Jumbo Domino

The magician shows a transparent bag full or various domino cards.

He asks a member of the audience to pick one. He then shows a giant domino (4-4) to the audience and announces that it is the same as the one that was selected. The spectator then complains that that's not right he had picked out the 6-6 domino card. The magician sadly acknowledges the mistake and then shows himself to be a master of his trade. All at the same time, 4 of the spots of the giant domino duplicate themselves and move into the correct positions! With this, the domino can be seen to have changed in full view into the 6-6 domino. The magician takes the wandering spots off of the giant domino saying -this was just an illusion- and gives the giant domino to the audience to be examined!
